ADDING AND RECORDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 770,446, datedSeptember 20, 1904. Application filed July 25, 1903. Serial No. 167,001.(No inodel.)

T 0 (ZZZ whom it may concern.-

Be it known that I, ARTHUR P. SIMPSON, a citizen of the United States,and a resident of the city and county of Sacramento and State ofCalifornia, have invented a new and useful Improvementin Adding andRecording Machines, of which the following is a specification.

This invention relates to improvements made in machines or devices thatare constructed to print and add figures and to record the sumtotal; andthe invention comprises certain novel parts and combination of parts, ashereinafter described, and pointed out in the claims at the end of thisspecification, reference being had to the accompanying drawings, formingpart thereof.

Figure 1 of the drawings is a side elevation of the machine, with thetop and sides of the case removed to expose the working parts inside,the view being taken from the left side of the machine. Fig. 2 is asimilar elevation taken from the right side of the machine. Fig. 3 is atop plan with the operating-keys removed. Fig. 4 is a longitudinalsection on line 4 4, Fig. 3. Fig. 5 is a rear elevation of the keyboard.Fig. 6 is a detail side view of the paper-feeding and platen-operatingmechanism, the left frame-plate being removed. Fig. 7 is a top plan ofthe carrying mechanism. Fig. 8 is a cross-section through Fig. 7. Fig. 9is a detail of the register-wheels. Fig. 10 is a front view of themachine.

This machine is composed of a setting mechanism composing thefinger-keys and parts actuated by them, a registering mechanism, and aprinting mechanism,which will be described in the order named.

The frame of the machine is composed of a base D, to which are securedthe side frames or plates A and B. To the front of these plates issecured the curved front plate C, and just below plate C and between theframeplates is secured the plate 4. (See Fig. 4.)

Loosely slidable in rectangular openings 2 and 99 in the plates C and 4are a plurality of vertical banks of ten finger-keys each, marked withthe numerals 0 to 9, inclusive, beginning with O at the upper key. Anydesirable number of rows may be employed,

four rows being here shown. The keys are positioned in vertical planesand radiate from a common center, which is preferably the center ofcurvature of the plates C and 4. On each key between the plates is aspring 6 to return the key to normal position. Pins 98 prevent the keysfrom being pushed out too far by their springs 6. Each key is providedwith two notches 79 and 5. Outside of the plate C are a series ofslotted slide-plates 7 6, normally held down by the springs 78, whichplates bear against the key and may lock them in depressed position byengaging in the notches 79. The notch 5 is tapered outwardly and servesto force the locking-plate upward, so that whenever a key is forced inthe locking-plate will be forced upward, so that it may be in positionto engage in the outer notch 7 9. hen a second key is pushed in, theupward movement of the locking-plate will release the first key. Thelocking-plates are provided with projections or lugs 81 at their lowerends, whereby they may be moved upward at will by hand, and thus anydepressed key be released.

Secured in the frame-plates A and B is a shaft 7, on which are pivoted aseries of double sectors 8, having upper segments 9 and lower segments10. These sectors are yieldably held in their normal positions by thesprings 12. The front edges of the sectors are grooved to receive theends of the keys. The keys are of varying length, depending upon theirposition and upon the angle of contact with the sector, and are soproportioned that whenever any key is depressed the segment 9 will beturned back a circular distance equal in length to one more tooth thanthe number indicated on the key depressed. Thus depressing the O keywill swing the segment back the space of one tooth, while depressing the9 key will force the segment back the space of ten teeth.

The registering Medea 222 8222. Journaled in the frame is a shaft 24, tothe right end of which is secured the operatinghandle 34, which may beswung forward about one hundred and twenty degrees or from the full tothe dotted positions of Fig. 2. On this shaft between the frame-platesare secured a series r of toes 33, one for each sector, and outside ofand adjacent to the frame-plates are secured on the shaft the disks 25and 26, each provided with a semicircular notch 27. Journaled in theframe-plates nearly above the shaft 24 is a shaft 21, on the outer endsof which is secured the register-frame 20, having depending arms 31,carrying rollers '110, that contact with the disks 25 and 26 andnormally rest in the notches 27. J ournaled in this register-frame is aslidable shaft 55, upon which are loosely mounted the register-wheels LB6 g, havmg numerals from 0 to 9 and Which are provided with ten toothedgears- 59. (See Fig. 3.) They are kept in place along the shaft by theguides 106. In the shaft are secured a series of pins 67, normallyout'of the path of pins 105 in the wheels 9; but upon sliding the shaftto the left and turning it by the knob 58 the pins 67 will engage thepins 105, so that the .register wheels may be turned to Zero. The shaftis held in place by the spring 108, Fig. 1. Secured to the gears 59arecams 68, the Office of which will be explained later. Each gear 59 excepting the one farthest to the left is located over a segment 9, sothatwhen the handle 3& is moved forward and the frame 20 permitted todrop the resetting of the sectors will turn the wheels g. (See Fig. 4.)As the rear teeth of sectors 9 are cut off the gears 59 will be turnedthe number of teeth indicated by the key depressed in that particularrow and not one more tooth, because of the extra distance the sector is,moved. The transmission of the tens is effected asfollows: On the shaft62, mounted in the frame 20. are slidably mounted a series of collars61, having fingers 60 and grooves 66. (See Fig. 3.) On the shaft nearone end is secured the segment 63, which meshes with the segment 64,secured to frame A in such amanner that when the gears 59 mesh with thesegments 9 the fingers 60 will be inclined downward; but when the frameis elevated, as in Fig. 1, shaft 62 will be turned and the fingers willbe inclined upward. (See Fig. 2.) hen the frame 20 is lowered, aplurality of collars 61 will contact with the end of springs 12 1, whichare secured to a cross-piece between the frames A and B. When a collaris moved to the left, as will be hereinafter explained, a spring willengage in the groove 66 and prevent the collar from slipping back.

Pivoted to the rear cross-bar 107 of the frame 20 for horizontal andvertical movement are.

the levers 65, which rest on the earns 68 in the path of the pins 57 onthe gears 59. v The outer ends of the levers lie in the grooves 66 ofthe collars 61. (See Fig. 7.) Projecting The operation of carrying is asfollows: The fingers 60 are normally between the gears 59 and wheels g,and swinging them up or down has no effect on the registers. henever the0 passes on the units-wheel 9, its pin 57 moves the end of the lever andthe finger 60, controlled by it, to the left in the plane of thetens-gear 59. If-the tens-gear were at 9, its cam would have lifted theend of its lever 65 into the path of the finger 73, controlled by theunitslever 65, and thus the tens-lever would also be moved and thefinger 60 on the collar controlled by the tens-lever moved into theplane of the hundreds-wheel. Upon the lifting of the frame20 the fingers60 thus positioned would each turn their gear one tooth. Thesame'inovements will occur with am of the other wheels Gr. Near the endof their upward stroke these collars 61'are moved to the right by thepins 71 engaging the cam-faces on the collars.

The printing mechanism.-Secured in the side frames A and Bare three rods51 100 100, upon which is hung a printing-frame composed of two sideplates 101, positioned by sleeves. (See Fig. 1.) Between them are aseries of gears 14:, loosely journaled on the shaft 102, which mesh withthe segments 10 of the sectors. Engaging these gears are pinions15,secured to the printing-wheels b, all loose on the shaft 17, carried bythe printingframe. The printing-wheels have ten projecting type for thenumerals 0 to 9 and one blank space. Upon the swinging of the sectorsthe corresponding printing-Wheels will be moved the requisite distanceto present the type of the numeral of the key depressed. hen no key isdepressed in any vertical row, no character will be printed on the paperstrip. The platen F is carried by two arms 18,'pivoted on the shaft 35.The width of the platen and the printing-frame is less than the width ofthe register, and the segments 10 of the outside sectors are thereforeofiset, as shown in Fig. 3. On the left end of the shaft 35 is securedthe lever 36, thelower end of which is provided with a pin 94:, thatpasses through a slot in the frame B and engages with the left arm 18 ofthe platen to swing the same against the printing-wheel. (See Fig. 6.)Pivoted on the pin 39 on the disk 26 is the spring-pressed dog 38, thatengages the upper end of the lever 36 during the forward movement of theoperating-handle, and thus turns the lever and swings the platen upward.The dog will swing out of the way of the lever on-the return stroke ofthe disk and handle.

The paper is fed forward by two rolls (Z and e. (SeeFig. a.) The roll eruns freely on a shaft carried inthe rear end of the platen. The roll (Zis fixed to a shaft journaled in the main fraine, and on its left end issecured a ratchet wheel 92. (See Fig. 1.) Loose on the outer end of theshaft isa gear 90, which meshes with the segment 10, journaled on theshaft .24. The arm 91, secured to the gear 90, carries the pawl 93,which turns the ratchetwheel 92. A pin 42 in the end of the arm 44, alsojournaled on the shaft 24:, may be positioned in any one of the holes 46as may be desired, and this pin, together with the stationary pin I1,causes the segment 40 to turn the gear to feed the paper a distancedepending on the hole &6 selected. It will be noticed-that the angulardistance between the pawl 38'and the end of the lever 36 is less thanbetween the pin 42 and the edge of the segment 40, so that the platenwill act before the paper is fed.

Supported by the printing-frame on trunnions 87 is a plate carrying anink-pad 86, which is moistened by the ink in the reservoir 88, having anoutlet and a top 89, provided with air-inlet 96. (See Fig. 4c.) Theinkingroller 50, carried on a rod secured in the lower ends of links 52,secured to the shaft 51, iscaused to swing by the arm 54:, secured tothe right end of shaft 51. The end of this arm 54L rests on the pin 104and normally holds the roller in the position shown in Fig. 4; but whenthe operating-handle has moved forward the lever 5% moves down and isheld there by the cam 53, and thereby holds the roller 50 over in frontof the printing-wheels. By these means only the types presented to theplaten will be inked. Just before the operating-handle returns to normalposition the lever 54 and the inking-roller will be swung back.

The platen is provided with a top plate or shield 97, that covers allthe paper excepting that portion under the opening 109. (Shown inFig.4:.)

Journaled in the main frame of the machine is a shaft 82, carrying theplate 85, which bears against a lug near the upper end of eachslide-plate 76. On the right end of this shaft is a lever 83 in the pathof the lug 84 on the disk 25. WVhenever the lever 34 is moved forward,the lug 8 L, contacting with this lever, forces all the slide-platesupward, thus releasing the depressed keys.

The operation of the various mechanisms in their order is as follows:After the desired keys have been depressed and the printingwheels setthereby the handle 34: is brought forward. At the beginning of itsstroke the frame 20 is lowered, engaging the gears 59 with the segments9 and lowering the fingers 60 through the operation of the segments 63and 6%. At the same time the inking roller is swung forward. Next thepawl 38 engages the lever 36 and swings the platen and paper against theprinting-wheels. Next the pin 42 engages the sector A0 to feed thepaper, and the lug 8 engages the lever 83 to release the keys, and,lastly, the toes 33 turn back the sectors 8 and advance the registerwheels. The parts remain in this position until just at the end of thereturn movement of the handle,

when the lever 54 will be raised and swing back the inking-roller, theregister-frame will be raised to move the gears 59 out of contact withthe sectors 8 by the lug 8 f contacting with the rollers 110, and thefingers 60 will be turned upward, thereby transferring the tens. Thetotal sum is shown by and is read from the register-wheels behind thekeyboard, from which it is transferred to and recorded on the paperstrip by setting the printingwheels as before by selecting the properkeys in the different series according to the required values andnumerical order and then printing the sum upon the paper. In thisoperation of recording the sum it will be noticed that the row offigures showing the result of the addition is necessarily printed overthe top instead of at the bottom of the columns.

In the event of an error made during the operation of printing thefigures in columns, the correct total can nevertheless be printed if themistake be discovered before the final operation of setting theprinting-wheels to record the total, because such operation iscontrolled from the keyboard and not directly by the adding mechanism,and a difierent total from that read from the register-wheels may beprinted where a mistake in any of the amounts previously set down isfound to have been made.
